Firstly reliance jio sim was coming with lyf mobiles as a offer and at that time jio sims service was good, there was very high internet speed of jio network but after the the comercial launce of reliance jio sim at 5 september they put a cap on jio sim network and after that the internet speed decreased to about 1-2 mbps and it is only 4 gb per day and they are saying that in reliance jio sim there is unlimited 4g and free voice calling.There is also a problem of call dropping in this reliance jio sim.There service is very bad, customer care dont pick our calls.
